About the Bulb black outline icon
A pear-shaped glass bulb sits on a ribbed screw cap with a small rounded contact tip, and eight short rays radiate from the top and sides to show it glowing. The shape is the standard shorthand for ideas, insight and electricity, useful for tips and hints panels, brainstorming slides, energy saving pages, startup landing sections and hint tooltips in apps.
The glass takes about two thirds of the height and the base is drawn as two stacked bands, leaving the interior empty rather than showing a filament. Pair it with gear, rocket and target icons in product sets; the rays can be removed for a quieter toggle state.
This is the black outline version of the bulb icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
